IMPROVEMENT IN DEVICE FOR S'IPPING- THE REVOLUTION OF SPINDLES IN SPIN- .NINGMACHINES, 8cc. v

The Schedule referred Ato in these Lettera Patent and making part of the same.

To all whoml it may concern:

Be it known that we, UGNE HURET and FRAN- cols L. DE BRUYN, of Gondette, Pas-de-Galais, Empire of France, have invented certain Improvements in Machinery for Preparing,l Spinning, and Doubling Cotton, and other iibrous substances; and we do hereby declare the following to be a full,'clear, and exact description of the same.

Our improvements consist of peculiar mechanism, fully described hereafter, by which any one ofthe spindles of a spinning-machine may be stopped instantane,ouslywithout interfering with the motion of the rest.

In order to enable others skilled in the art to make and use our invention, we will now proceed to describe its construction and operation, reference being` had to the accompanying drawing, which forms a part of this speeiiication, and in which- Figure 1 is a transverse sectional view of suiiicier of `a spinning-machine, toillustrate our improvements;

Figure 2, a longitudinal section of the same; an'd Figure 3, adetached view of part of the mechanism.

` Similar letters refer to similar parts throughout theV several views. v l Hrepresents thedriving-shaft, and G G, two of th bars of the frame of a spinning-machine, A being one of a number of spindles, arranged to turn and to have a limited sliding motion in sleevesor bearings F and F', which are properly iitted to the said bars G G.

At the upper end of the spindle A is a iiier, of

the usual construction', and near its lower end is a disk, C, of compressed leather, or equivalent material, bevelled or conical on the under side, and this disk is conh'ned between a weight, B, and metal washer D,

the ypressure of the latter against the said disk being regulated by a nut, E, which .is adapted to a screwthread on the spindle. Y

Ihe lower end ot' the spindle does not turn in a step, as usual, but is supported by a wheel, I, of metal, upon the bevelled edge of which the bevelled portion of the leather washer C rests, and it should be understood that' the driving-shaft is furnished with as many of these wheels I as there are spindles, each of the latter having its own bevelled washerO.

As the weight B causes the washer to bear upon the wheel I with considerable pressure, it follows that when the latter is turned, the spindle will be rapidly :'otated; a'nd in order to stop the motion of the said spindle, Without interfering with that of the drivingfrom the wheel I.

The operation ofthe rod K is clearly shown inv fig. 3, where it .will also be observed, that owing to .the shape of its upper slot L, the said rod may be prevented from falling from the position to which it is raised.

Although we have hitherto referred to the washer as being of leather, in contact with the bevelled edge of a metal disk, both parts may be of leather, or other hard and insonorous substance. Caoutchouc, hard- .ened wood, lead, or gutta-percha may be used for the disk on the spindle, the other being of iron, or both may be made-ot' any of these different substances.

' The important object is to have a material or composition which is hard, compact, homogeneous, and susceptible of being turned to a proper form.

By driving theI spindles as above'described, a very rapid and noiseless motion is attained, while the eiect is as preciseA as that resulting from the most perfect cog-gearing.

We would also 'observe that our friction-gear and disconnecting-device are applicable to preparatory machines, to continuous orself-acting spinning-frames, and also to twisting-frames in general and to the treatmen of different fibrous substances.

We claim as our invention, and desire to secure by Letters Patent- The combination of the driving-mechanism herein described, the spindles A, and the plates K, provided with slots L L, and bent ends, all constructed andarranged for adjustment on the frame of a spinning-machine, as specified.

In .witness whereof', we have signed our names to this specification, in the presence of two subscribing witnesses.
